TLD rewrites are now deprecated

We should add the root domain (aka "tld") as the host or an alias to the site.
They can then point the A records at our CDN Anycast IPs and they will be
redirected by Bouncer. Those IPs are:

23.235.33.144

and:

23.235.37.144
The rest of this sentence is now inaccurate, and might therefore be confusing. Explaining that we can now point these domains at our CDN for clarity also explains why the `tld` directory is deprecated.
